Options on this test car included $14,400 worth of carbon fiber draped over every imaginable surface including the engine bay; a $6,400 Bang and Olufsen sound system; and a $2,500 system called AMG Performance Media, a frighteningly distracting software system that tracks and displays on the navigation screen data such as engine output and throttle position, a g-force meter and laps times.
